简介
opensearch是一个社区驱动的数据存储和搜索引擎，基于es修改License之前的最后一个版本开发，安装流程其实和elasticsearch差不多
项目地址
https://opensearch.org/
操作
首先拉helm模版
helm pull opensearch/opensearch --version 2.4.0
helm pull opensearch/opensearch-dashboards --version 2.3.0
解压
tar -zxvf opensearch-dashboards-2.3.0.tgz
tar -zxvf opensearch-2.4.0.tgz
修改values.yaml
修改opensearch 相关参数
opensearch 这里我只修改storageClass
storageClass: "nfs-client"
要注意的是，如果你的vm.max_map_count小于262144会报错
你可以在kubelet中加上
allowed-unsafe-sysctls
相关参数，然后修改values.yaml开启
sysctl:
enabled: false
具体的可以看
https://kubernetes.io/zh-cn/docs/tasks/administer-cluster/sysctl-cluster/
我这里为了方便只能手动修改节点中的vm.max_map_count
之后加个ingress
ingress:
enabled: true
# For Kubernetes >= 1.18 you should specify the ingress-controller via the field ingressClassName
# See https://kubernetes.io/blog/2020/04/02/improvements-to-the-ingress-api-in-kubernetes-1.18/#specifying-the-class-of-an-ingress
# ingressClassName: nginx
annotations:
kubernetes.io/ingress.class: nginx
# kubernetes.io/tls-acme: "true"
path: /
hosts:
- opensearch.xxxxx.com
tls: []
# - secretName: chart-example-tls
# hosts:
# - chart-example.local
修改opensearch dashboard相关配置
dashboard这里就加个ingress就好了
ingress:
enabled: true
# For Kubernetes >= 1.18 you should specify the ingress-controller via the field ingressClassName
# See https://kubernetes.io/blog/2020/04/02/improvements-to-the-ingress-api-in-kubernetes-1.18/#specifying-the-class-of-an-ingress
# ingressClassName: nginx
annotations:
kubernetes.io/ingress.class: nginx
# kubernetes.io/tls-acme: "true"
hosts:
- host: opensearch-dashboard.xxx.com
paths:
- path: /
backend:
serviceName: ""
servicePort: ""
tls: []
禁用安全插件
一般来说上面配置完成之后apply就好了，但是为了简单方便做开发可以禁用掉安全插件
详细的可以看下面
https://opensearch.org/docs/latest/security-plugin/configuration/disable/
首先配置opensearch
plugins:
security:
disabled: true
之后配置dashboard
重新创建一个Dockerfile
FROM opensearchproject/opensearch-dashboards:2.2.0
RUN /usr/share/opensearch-dashboards/bin/opensearch-dashboards-plugin remove securityDashboards
COPY --chown=opensearch-dashboards:opensearch-dashboards opensearch_dashboards.yml /usr/share/opensearch-dashboards/config/
创建一个配置opensearch_dashboards.yml
server.port: 5601
server.host: "0.0.0.0"
server.name: "dashboards"
opensearch.hosts: ["http://opensearch-cluster-master:9200"]
logging.dest: stdout
之后build一个image在values.yaml中修改掉镜像名字就好了
最后
使用argocd去推送就好了,还有目前opensearch dashboard是不支持中文的
